q
How do polyunsaturated fats affect my health?


a
Polyunsaturated fats can have a beneficial effect on your health when consumed in moderation and when used to replace saturated fats or trans fats.  Polyunsaturated fats can help reduce the cholesterol levels in your blood and lower your risk of heart disease. 

They also include essential fats that your body needs but can’t produce itself – such as omega-6 and omega-3.  You must get essential fats through food.

Omega-6 and omega-3 play a crucial role in brain function and in the normal growth and development of your body.

q
How much polyunsaturated fat should I eat in a day?


a

The fats in the foods you eat should not total more than 25–35 percent of the total calories you eat that day and, for good health, the majority of those fats should be monounsaturated, polyunsaturated or both.  Eat foods with monounsaturated fats and/or polyunsaturated fats instead of foods with high levels of saturated fat or trans fat.  For practical tips, learn how to Live Fat-Sensibly.
